ISOVAC

isovac® energy-efficient electrical steel, fully machined and semi-machined

isovac®, our non-grained electrical steel for the highest energy efficiency, provides you with a comprehensive service package and the best overall package of benefits.

Thanks to the continuous rolling and annealing processes, all isovac® brands guarantee the homogeneity of the material in terms of its mechanical, geometric and magnetic properties. This ensures stable processing of the material and guarantees the consistent quality of each roll and grade of steel.

As a leading manufacturer of electrical steel strip in Europe, we supply a wide range of product groups. Many of our steels are available in standard or premium grades.

isovac® HP high perm: specialist with the highest permeability

Optimal texture settings increase magnetization and reduce core losses. This increase in efficiency allows the same level of performance to be maintained while reducing the size of components and saving materials, weight and cost. This means that a higher level of performance can be achieved with the same component size.

• Increased performance is achieved due to increased torque based on higher magnetization
• Cost optimization thanks to less material use, less weight and less space

isovac® HF High Frequency: specialist for high frequencies

The use of isovac isovac® HF (high frequency) brands guarantees optimal use of the equipment at higher frequencies. High-precision adjustment of the microstructure and adaptation of the alloy content make it possible to maintain low losses in the high frequency range.

• • Application in high-speed lathes with small losses in the core at high rotation speeds
  • Greater design freedom and engine size optimization based on greater strength

high-strength isovac® HS: specialist for demanding mechanical requirements

Both magnetic and mechanical properties play an important role in many modern high-speed motors or large electrical machines. The electrical steel used, especially in the rotor, is subjected to high mechanical loads, so it is so important to use a high-strength material. isovac® HS (high strength) grades combine good magnetic properties with high strength. We can supply the kind of material that our client requires. Our isovac® HS grades can be customized for increased strength, a higher degree of core compactness and a highly innovative Backlack.

• Decreasing the air gap between the rotor and the stator as a result of greater strength or reducing the width of the rotor crest in permanently excited machines
• Greater design freedom for electric machines
• The possibility of partial further annealing at the customer’s place in order to improve the magnetic properties, for example, in the stator

isovac® HC high-conductivity – Der Spezialist mit hoher thermisker Leitfähigkeit

Durch seine hohe thermic Leitfähigkeit sorgen isovac® HC (high conductivity) Güten für eine rasche Wärmeabfuhr in Kombination mit höheren Polarizationen bei gegleichzeiten niedrigen Ummagnetisierungsverlusten. Innovative design strategies have become possible for electric machines

• Potential savings in electric machines due to smaller component sizes and lower material usage due to higher polarization.
• Cooling power is reduced by up to 20% due to higher thermal conductivity
• Alternative engine designs with reduced scrap volumes based on low strength

isovac® NO: specialist in electromobility

The alloy design of isovac NO grades, its high-precision microstructure and sheet thickness ≤ 0.35 mm make it particularly suitable for applications in the high frequency range and for high speed motors. isovac NO grades achieve an optimal balance between magnetic and mechanical properties, which makes it possible to create new structures in the automotive industry.

• • Reduced energy consumption when used in engines with the highest rotational speeds
  • High strength while maintaining low losses makes the material very suitable for rotors and stators.
  • Coatings with innovative electrical steel insulation systems on request: pre-designed for use in combination with Backlack

isovac® HE high efficiency: the specialist for reducing the final annealing time

isovac® HE (High Efficiency) has a high degree of decarbonization as delivered, which means that the customer’s final annealing time can be significantly reduced. Further annealing at the customer completely excludes any mechanical damage to the material during the stamping process.

• • Final annealing time is significantly reduced due to low carbon content
  • Overall cost reduction due to low energy consumption, low emissions and higher productivity
